Two methods,dipping of Zr(OH) 4 or ZrO 2 support in aqueous solution of Cu(NO 3) 2·4H 2O were adopted to prepare supported copper oxide on ZrO 2.Extensive characterization has been done on the physical-chemical properties of the system.In the TPR experiments,four TPR peaks were observed.In conjunction with the observation by XRD,it was concluded that highly dispersed copper(II)oxide and bulk copper(II)oxide were reduced to metallic copper,giving pesks α and β,γ and δ,respectively.Suface ocygen species were easily desorbed and reduced,and which leads to highly active for CO oxidation.
